Welcome to Ren One, a bustling Martian colony home to a stubborn girl. Zayna has always seen herself as a plant and animal-loving geek with a tomboy's heart, but she's never really needed to use her adaptability…until now. When Mars is cut off from Earth, the ordinary descends into a high-stakes fight for dwindling resources as some grasp the opportunity to seize power. Zayna knows she'll need the help of her new boyfriend and ex best-friend-forever not just to get out of this alive, but to prevent her from losing the only family she has left. What she doesn't realize is that the clue to the future might not be inside the colony, but lying secretly within Mars itself.
